There was a bug in the DisplayList code for layers where we would set the alpha value for a layer only if the alpha were non-1. This works most of the time (since the value is usually 1 and doesn't need to be set at all, and if the value is non-1, it is set correctly). But when the value has been set to a non-1 value, setting alpha back to 1 cannot happen due to this logic. This caused launcher to have some invisible pages when returning to Home because those pages previously had an alpha value of 0, and setting the alpha to 1 had no effect due to this DisplayList code. The fix is to simply remove the check for non-1 values; we should always set the alpha value of layers to handle all cases.
